UMUBROVED SUBMARINE PLOUGH.

To ALLr WHoM 1T MAY ooNeERN: H e Be 'it' known thatI, EDWIN T. LIQQN, of Demopclis, in the count),Y 'ot Marengo, md Smm f-Afbmlgrhllrm invented a new and useful Improvement in Submarine Piough and do hereby declare that the follonyingiene.'

full, clear, and exact deseiiption'theieof, which will enable others skilled in the art to make and use thesmn reference being had to the accompanying drnwings, foi-[ning part of this specification.`

This invention consists in attaching to the side of a steamboat o1' other vessel a submarineplough, which` by its action on the 'bottom of rivers and other waters `(lispl'aces the sand-,"mnd', and.othervloscznxaterial, :cnil

thereby excni'vate's aV channel and. deepens the water `for purposes of navigation. vo'i vfor other purposes;` thc f `machine being so constructed that while the sand or mud is loosened by" the plough a strong under-:cni'r'ent,isf I prodncedby a discharge of water from a-powei'ful force-punipth'rongh a hose, as nill'h'e hereinafter described.'

Figure lrepresents a. top view of the plough, and' Figure i?. a sid'e view. n l Similar letters of reference indicate like parts.

A represents e freine, which is rectangular in form., towhieh the parts of the-machine areuttached. B 'mc i two cross-pieces which are attached to the side pieces of the fmmeby pivots which allow them to turn or `rol'l."

The pivots or tenons on 'Which'they turn nre seen in dotted lines in the drawing. C C 'epresentnrms ivh'icliare attached t'o the piecesB B, as seen in iig. 2.l` D represents the plough proper. This is of [.yeculioiform, .being y in its cross-section a circular trough withv one of the lsides extending donjin-which' sideis marked i. upc-nca' are placed wings, c c, which project laterally,-somewha.t like themould-boerd of n confiinonplough. -Aboiielthese wings c there .projects another ciijcular ning, d, .through the-middle of whichlthcie is .an aperture? which Lopens between theA Wings cc, as seen at c. To, this `epei'ti'n'e is connected o. short piece of' metallic' pipena to the pipeis attached' a flexible hose-marked g, which hose 'is Vconnected iv-ithn force-pump, H isnperosfshead which slides on thesides of the 'frenie'A. -J'J are :mns which are attached tothe cross-head nndtotlie plough D, as seen in the-dressing. 7c isarod which is lattached tothe cross-'head `atp-its V.inner end, and'ivhich passes through the frame, with a. screw-nut, n, on its end. h is a sleeve which posses through the frame, ai en oilwhichis governed hcehuin N from the boot.
